Screen Sharing and power management with GTX 650 Ti

I have a problem with my ASUS GTX 650 Ti OC card. When I connect to my OSX machine via Screen Sharing, GPU and memory clock will go up to highest values, and stays here until a restart. Even if I close Screen Sharing, the clocks still locked on the highest values. This problem exists on 10.9.5 and 10.8.5 too. I have tried with the default OSX driver, and also nVidia web drivers. I am using an SSDT for my i7-2600 and a DSDT for my motherboard. Any help would be appreciated, because my computer is on 24/7 and using services like file and screen sharing is essential. Thanks!

No ideas?

I have several EVGA GTX 650 Ti's and haven't see those problems. What's your card make/model #?

It's an Asus OC model.
